Master-slave multi-level gsm remote feedback intelligent door lock and its encryption algorithm based on encrypted SMS

Abstract

The invention is a master-slave multi-level remote control feedback smart door lock based on encrypted text messages and its encryption algorithm. The hardware includes a client, a communication unit, a master control unit, a fingerprint identity verification unit, a current limiting protection module, a voice broadcast unit, EEPROM, touch display screen, relay and door lock; the communication unit receives and recognizes client command information through the GSM network, the communication unit is connected to the main control unit through the USART, the main control unit is connected to the relay through the current limiting protection module, and the relay controls The door lock bayonet is opened and closed; the fingerprint identity verification unit is connected to the main control unit through the USART, and the fingerprint information is read and compared. The voice broadcast unit is connected to the main control unit through the USART to realize real-time voice status feedback. Connect to realize the storage and extraction of the number information of the master and slave machines. The present invention, one machine at a time, one encryption, greatly enhances the safety performance on the basis of reducing the operation of the single-chip microcomputer.

Description

technical field [0001] The invention relates to the technical field of remote control, in particular to a GSM remote feedback intelligent door lock with multiple control levels for encrypted text messages and an encryption algorithm thereof. Background technique [0002] As people's requirements for quality of life increase, face-to-face real-time control devices can no longer meet people's needs. Combined with the popularity of smart phones and the improvement of smart phone security performance, remote control has become the mainstream of life today. [0003] As long as the remote control products currently on the market are based on WI-FI, Bluetooth, and infrared control, the control distance is relatively high, the safety performance is poor, and the stability performance is not strong, and most of them need to download specific control terminals such as corresponding APPs. The level of control authority is not distinguished, which makes it easy for illegal personnel to ...

Problems solved by technology

[0003] As long as the remote control products currently on the market are based on WI-FI, Bluetooth, and infrared control, the control distance is relatively high, the safety performance is poor, and the stability performance is not strong, and most of them need to download specific control terminals such as corresponding APPs. The level of control authority is not distinguished, which makes it easy for illegal personnel to seize control

However, the security of smart door locks is very troublesome for RSA to generate keys. Due to the limitation of single-chip computing speed and prime number generation technology, it is difficult to achieve one-time encryption. This affects the security performance of frequently used remote control, and Greatly increase the amount of data calculation
